Uranium One is a distraction. It won’t be investigated, it’s not tied to the Trump-Russia Collusion charges that Mueller is working under. I’d say his whole investigation is looking to tie money trails back to the President for years back. He’ll indict Donald Jr and Jared first to box in the President on any pardons for others. Mueller has been playing multi-dimensional chess.
I think your characterization of this investigation is completely off base. It might have made sense a few months ago, but with each passing week I’ve gotten more certain that the Trump team was never really the target here.
